ATA/SATA/SCSI instruction, therefore, no matter what type of hard drive can be used. Its functions are: scanning the surface of the disk, clearing, viewing the SMART property, running Selftest SMART testing, adjusting the hard drive aam (noise management), apm (power management) and other parameters.

Why use Scan HDD? U盘之家

When your computer is out of response, it is caused by the failure of the hard disk. Then you need a tool to make a more precise diagnosis of hard disk has what fault; in most cases hard disk failures are not physical or non fatal, using the simple method can repair; in addition, hard disk recovery and data recovery engineers also need a tool to the hard disk failure of preliminary diagnosis and repair -- HDD scan provides the functionality you need. www.upan.cc

Scan HDD based on the ATA/SATA/SCSI specification, the use of interface commands for the diagnosis and repair of hard drive. Scan HDD runs on the Win2K/Xp operating system, using API to access the hard drive. If the interface of the hard disk and the lower part of the failure occurs, then the Scan HDD will not be able to detect the hard drive, and even lead to the operating system can not start.

ATA/SATA/SCSI指令，因此，不论是何种型号的硬盘都可以使用。它的功能有：扫描磁盘表面，清零，查看SMART属性，运行SMART Selftest测试，调整硬盘的AAM（噪声管理），APM（电源管理）等参数。  U盘之家

为什么要使用HDD Scan？

当你的计算机失去响应，经过检测发生是由硬盘故障引起。这时就需要一种工具来更精确的诊断硬盘发生了何种故障；大多数情况下硬盘的故障不是物理性的或非致命的，使用简单的方法就可以修复；另外，硬盘修复和数据恢复工程师也需要一种工具来对故障硬盘进行初步的诊断和修复——HDD Scan就提供了你所需要的功能。

HDD Scan基于ATA/SATA/SCSI规范，使用接口指令对硬盘进行诊断和修复。HDD Scan运行于Win2K/Xp操作系统，使用API访问硬盘。如果硬盘的接口以及更底层的部分发生了故障，那么HDD Scan将不能检测到硬盘，甚至会导致操作系统不能启动。
